You have a psychic link to your decks, so you know where to draw what card you wanted to use, you can use any card at anytime but you can only use 4 per post.

Okay, but I'm still confused on how to visually imagine this. Are the cards actually cards inside of the arena? If you play one, how are they played? Is it like Persona where they appear for a second, you break them and then the effect happens or more like YGO where it appears in your hand and you toss it somewhere to play it?

Sorry if I ask a lot of questions, but I like details.
